Hey guys, built my new rig around Christmas and kept the heat sink that came with my processor.
It runs normally at around 50-52 C. What do you guys think would be a good heatsink for my rig?
Here's what I have:

Intel Core 1-7 970 (3.2GHz, haven't overclocked it yet)
Intel DX58SO motherboard
2x Samsung 2TB hard drives (RAID 1)
2x Radeon 5770 Turbo cards (would have liked nvidia, but I got a deal on these)
16GB Corsair RAM
Thermaltake 1000W power supply
Samsung Blu-Ray burner
CM 690 II Advanced case

Any and all help would be appreciated :]
